Question
In a hydrogen atom, the electron is in nth exited state. It any com down to second exited state by emitting ten difference wavelengths. What is the value of n ?
Options
A.6
B.7
C.8
D.5
Solution
10 = nC2 ⇒ n = 5 ; then 5 orbits are involved upon coming to second exited state
so nth existed state is 6th [2nd, 3rd , 4th, 5th, 6th]
so nth existed state is 6th [2nd, 3rd , 4th, 5th, 6th]
